6 Claims. (Cl. 101-479) In highspeed web perfecting rotary presses where quick drying inks and web heating and cooling units are employed, it is very desirable that the several units be so located with respect to each other as to produce the best results while occupying a minimum amount of space.

The object of my invention is to so locate the printing and combined heating and cooling units, the web supply roll and the delivery, that the web can be fed and printed and the inks dried with a. minimum travel of the web.

My invention comprises, generally, first and second multicolor printing units, oifset from each other and located in substantially the same horizontal plane at opposite ends of the press, each printing unit consisting of an impression cylinder and form cylinders (in the present instance five form cylinders) arranged partway around the same; first and'second combined o heating and cooling units located side by side in line with and above their respective printing units, each combined heating and cooling unit comprising a heating cylinder and one or more (in the present instance two) cooling cylinders 25 and a web supply roll located in between the printing units and in line with the first units; means being provided for passing the web from the supply roll to and through the first units, then around turning bars to and through the 39 second units, and finally delivering the web.

A practical embodiment of my invention is represented in the accompanying drawings, in which Fig. 1 represents a diagrammatic view in top 85 plan; and

Fig. 2 represents a similar view in side elevation.

The first printing unit is herein represented as a five color unit, the impression cylinder being denoted by I and its five form cylinders by 2, 3, 4, 5, 6, which form cylinders are arranged partway around the impression cylinder I. The inking mechanisms for the form cylinders are denoted by 2a, 3a, la, in, 6a. The second printing unit for perfecting the web is herein represented as a five color unit, the impression cylinder being denoted by I and its five form cylinders by 8, 9, In, H, H, which form cylinders 50 are arranged partway around the impression cylinder 7. The inking mechanisms for the form cylinders are denoted by 8a, 9a, Illa, Ila, lZa.

These two printing units are arranged offset 55 from each other and in substantially the same horizontal plane at the opposite ends of the press.

The first combined heating and cooling unit is herein represented as comprising a large heating cylinder l3 and two small cooling cylinders 5 I4, l5, arranged at one side of the heating cylinder (preferably the left side) and spaced the required distance apart.

The second combined heating and cooling unit is herein represented as comprising a large 10 heating cylinder l6 and two small cooling cylinders l1, l8, arranged at one side of the heating cylinder (preferably the right side) and spaced the required distance apart.

These two combined heating and cooling units 15 are located side by side between the two printing units, above and in line with their respective printing units.

The web supply roll is denoted by l9 and it is located between the two printing units, in line with the first printing unit and the first combined heating and cooling unit.

The web is led through the press as follows: The unprinted web passes from the supply roll I 9, to and through the first printing unit where the web is printed in multicolor upon one side thereof. The web is then led to and around the heating cylinder 13 and cooling cylinders l4, l5 of the first combined heating and cooling unit. From thence the web is led around a turning bar 20 3 located below the said heating and cooling unit laterally to and around a second turning bar 2| located below the second heating and cooling unit. From thence the web is led to and through the second printing unit and from there to and around the heatingcylinder l6 and cooling cylinders ll, I8 of the second combined heating and cooling unit. From thence the perfected web is delivered from beneath the second heating and cooling unit in a path in line with and at the opposite end of the press from the second printing unit.

The means for driving the several units is not shown or described herein, it being understood that the first and second units may be driven separately if so desired, either for the purpose of making ready or for permitting a single or two separate non-perfecting multicolor products to be produced.

It will be understood that guide rolls are provided for passing the web, in connection with the turning bars, in prescribed paths from the web supply roll IT to the delivery.

It will also be understood that any suitable heating medium, such as steam, may be supplied to the heating cylinders l3 and I6 and that any suitable cooling medium, such as water, may be supplied to the cooling cylinders l4, l5 and l1, l8.

It will also be understood that any well known or approved quick drying inks may be used in the printing units.

What I claim is:

1. In a web perfecting rotary press, first and second multicolor printing units offset from each other at opposite ends of the press, first and second combined heating and cooling units located side by side between the printing units and in line with their respective printing units, a web supply roll located in line with the first printing unit, and means for leading the web through said units and delivering the web.

2. In a web perfecting rotary press, first and second multicolor printing units offset from each other at opposite ends of the press, first and second combined heating and cooling units located side by side between the printing units and in line with their respective printing units, a web supply roll located in line with the first printing unit, and means for leading the web through said units and delivering the web in line with and at the opposite end of the press from the second printing unit.

3. In a web perfecting rotary press, first and second multicolor printing units offset from each other at opposite ends of the press, first and second combined heating and cooling units located side by side between the printing units and in line with their respective printing units, turning bars located below their respective heating and cooling units, a web supply roll located in line with the first printing unit, and means for leading the web through said units and around the tuming bars and delivering the web.

4. In a web perfecting rotary press, first and second multicolor printing units oflset from each other at opposite ends of the press, first and second combined heating and cooling units located side by side between the printing units and in line with their respective printing units, turning 5 bars located below their respective heating and cooling units, a web supply roll located in line with the first printing unit, and means for leading the web through said units and around the turning bars and delivering the web in line with 10 and at the opposite end of the press from the second printing unit.

5. In a web perfecting rotary press, first and second multicolor printing units offset from each other at opposite ends of the press, first and sec- 15 0nd combined heating and cooling units located side by side between and above the printing units and in line with their respective printing units,

a web supply roll located in line with the first printing unit, and means for leading the web 20 through said units and delivering the web in line with and at the opposite end of the press from the second printing unit.

6. In a web perfecting rotary press, first and second multicolor printing units offset from each 5;,

other at opposite ends of the press and located in substantially the same horizontal plane, first and second combined heating and cooling units located side by side in substantially the same horizontal plane between and above the printing units 0 and in line with their respective printing units, turning bars located below their respective heating and cooling units, a web supply roll located in line with the first printing unit, and means for leading the web through said units and around 3 the turning bars and delivering the web in line with and at the opposite end of the press from the second printing unit.
